crth2/dp2 receptor

CAY10595 is an antagonist of the CRTh2 (DP2) receptor with a Ki of 10 nM.

BI-671800 (AP-761) is a highly specific and potent antagonist of chemoattractant receptor-homologous molecule on Th2 cells (DP2 CRTH2). With IC50 values of 4.5 nM and 3.7 nM for PGD2 binding to CRTH2 in hCRTH2 and mCRTH2 transfected cells, respectively. BI-671800 has the potential to treat poorly controlled asthma[2].

AZD1981 is an effective and specific CRTh2 (DP2) receptor antagonist (IC50: 4 nM), showing >1000-fold selectivity over more than 340 other enzymes and receptors, including DP1. AZD1981 has been used in trials studying the treatment and basic science of As

CAY10471 Racemate (TM30089 Racemate) is a potent and highly selective CRTH2 DP2 receptor antagonist. It binds to human CRTH2 DP2, DP1, and TP receptors with Ki values of 0.6, 1200, and >10,000 nM, respectively.

MK-8318 is an effective and selective antagonist of the CRTh2 receptor (Ki: 5.0 nM).

The biological effects of prostaglandin D2 (PGD2) are transduced by at least two 7-transmembrane G protein-coupled receptors, designated DP1 and CRTH2/DP2. In humans, CRTH2/DP2 is expressed on Th2 cells, eosinophils, and basophils where it mediates the chemotactic activity of PGD2. CAY10597, as a racemic mixture, is a potent CRTH2/DP2 receptor antagonist that binds to the human receptor with a Ki value of 37 nM. The R enantiomer is slightly more potent exhibiting Ki values of 23 and 22 nM at the human and murine CRTH2/DP2 receptor, respectively. The R enantiomer of CAY10597 inhibits eosinophil chemotaxis induced by 13,14-dihydro-15-keto-prostaglandin D2 with an IC50 value of 40 nM.

11-Keto Fluprostenol, a potent analog of prostaglandin F2α (PGF2α), primarily interacts with the FP receptor. It is a structurally modified derivative of prostaglandin D2 (PGD2) designed to enhance its potency and extend its half-life. The compound is produced by oxidizing fluprostenol at the C-11 position, which results in 11-keto fluprostenol. This modification allows 11-keto Fluprostenol to exhibit moderate affinity for the CRTH2/DP2 receptor, though it shows negligible activity at the DP1 receptor, distinguishing its action from that of PGD2.

CRTH2-IN-1 is a selective prostaglandin D2 receptor DP2 (CRTH2) antagonist, a Ramatroban analog, with an IC50 of 6 nM in the human DP2 binding assay.

L 888607 is an effective and selective CRTH2 agonist (Ki: 0.8 nM).

AMG-009 is a selective and potent dual antagonist of CRTH2 and DP, with an IC50 value of 3 nM for CRTH2 and 12 nM for DP receptors.

15(R)-15-methyl Prostaglandin D2 (15(R)15methyl PGD2) is a synthetic analogue of PGD2 and a selective and potent CRTH2 DP2 receptor agonist that modulates eosinophil CD11b expression, actin polymerisation and chemotaxis.
